To aZZ whom it may concern.-

Be it known that I, LARs CHRIST PEDERSON, a citizen of the United States, residing at Milltown, in the county of Polk and State of Wisconsin, have invented a new and useful Combined Heating and Cooking Stove, of which the following is a specification.

This invention relates to stoves, and espeeially to that class of combined heating and cooking stoves which are usually known as parlor cooking-stoves.

The invention has for its object to simplify and improve the construction and operation of this class of stoves, to present a stove in which various kinds of fuel (coal as well as wood) may be consumed, to provide in a stove of this class a bake-oven which shall be well heated, so that the best results in baking may be attained, and, generally speaking, to present a device of the class referred to which shall possess superior advantages in point of simplicity, durability, economy of operation, and general efliciency.

With these and other ends in view, which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of embodiment of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that the right is reserved to any changes, alterations, and modifications to which recourse may be had within the scope of the invention and without departing from the spirit or sacrificing the efliciency of the same.

In said drawings, Figure 1 is a vertical sectional view of a stove constructed in accordance with the principles of the invention, the same being taken on the plane indicated by the line 1 1 in Fig. 2. Fig. 2 is vertical sectional view taken on the plane indicated by the line 2 2 in Fig. 1. Fig. 3 is a horizontal sectional view taken on the line 3 3 in Fig. 1. Fig. at is a horizontal sectional view taken on the line 4 4: in Fig. 1.

Corresponding parts in the several figures are indicated throughout by similar characters of reference.

The base 1 of the improved stove is supported upon legs, 2 2, and said base constitutes the ash-pit 3, in which may be placed an ash-pan at, which is accessible through a door 5, having a draft-opening 6, controlled by a valve 7. A shelf 8 has been shown as projecting beneath the door.

The top of the base is composed of a plate 9, detachably supported upon lugs or flanges 10. This plate, which constitutes the bottom of the fire-box, is provided with draft-apertures 11, and it is provided upon its under side with flanges 12, serving for the support of a movable grate 13, the solid portion of which may be so disposed as to close the apertures 11, thereby preventing upward draft through the ash-pit. \Vhen coal or other fuel is used, in the combustion of which a large quantity of oxygen is required, the grate, which is provided with an operating-handle 14, is adjusted in a position which will leave the draftapertures 11 unobstructed. WVhen wood is the fuel to be consumed, the grate will preferably be adjusted to obstruct the apertures 11.

A tubular section 15, constituting the firebOX, is fitted within the walls of the base and is supported upon the plate 9. The section 15 is provided with a feed-door 16, having draft-apertures 17, controlled by a'valve 18. The tire-box section 15 is provided near its upper edge with interiorly-disposed lugs 19, supporting a plate 20, provided at its rear end with a downturned flange 21, which is spaced from the extreme rear end of the firebox by an obstructing-lug 22, disposed in the path thereof. The space or opening 23 between the rear end of the plate 20 and the rear wall of the lire-box is for the upward passage of products of combustion, and owing to the presence of the lugs 22 it will not be possible for the plate 20 to become shifted so as to obstruct said passage. The fire-box section 15 supports a plate 2%, which constitutes the bottom plate of the oven and which is provided with a downward-extending flange 25, exteriorly engaging the walls of the firebox. The plate 2% is provided at both its ends with slots or openings 26, surrounded by collars 27. Said plate or oven bottom is provided with openings 28, which are flanged or shouldered to support detachable lids or griddles 29 of ordinary construction. These griddles may be used in connection with ordinary reducing-rings, as 30. The plate 24, which is spaced from the deflecting-plate 20 in the top of the tire-box, is thus adapted to support pots, kettles, or similar cooking utensils, and the plate 20 is provided with openings 31, registering with the openings 28, so that the cooking utensils employed may be subjected to the direct action of the flames or the incandescent contents of the fire-box when the griddles are removed. Another important reason why the plates 20 and 24 are spaced apart is the provision thereby afiorded for the products of combustion to rise through the openings 31, so that while the direct draft is upward through the opening 26, registering with the draft-passage 23, a considerable portionof the products of combustion will be deflected in a forward direction and caused to pass upwardly through the opening 26 at the front end of-the plate 24:.

The oven-section 32, which is supported upon the plate 24, is provided with flues 33, the lower ends ofwhich exteriorly engage the collars 26. The top 34: of the oven-section is provided with openings 35 at the upper ends of the flues 33, and one side wall ofsaid section is provided with doors 36, through which the interior, which constitutes the oven,is accessible. The oven section is provided with an upwardly-extending flange 37, which is exteriorly engaged-by the side walls 38 of a section constituting a smoke-chamber and into which the products of combustion may rise through the openings 35 at the upper end of one of the flues 33, the other flue being stopped or obstructed by a movable plate 33*,said plate being movable in the sense that it is capable of being transferred from-one to the other of the flues 23.v This, however, may be accomplished only by separating the stove-sections, and this socalled movable plate is intended to be placed in the position which it is intended to occupy when the stove is set up. Within this section or smoke-chamber, however, is placed an approximately- U-shapd plate having a concave upper surface and provided at one end thereof with supporting-lugs, as 39. This plate, which is designated 40, constitutes a deflector whereby the upper end of the flue in which the plate 33 is placed may be further obstructed, and this plate or deflector is preferably made reversible, so that the opening 35, over which the. plate 33 has been placed, maybe obstructed, the concave upper surface of said plate 40 serving to deflect the products of combustion in the direction of the walls of the smoke-chamber. This smoke-chamber is accessible through a door 41 to enable it to be cleaned occasionally, as required. The position ofthedefiecting-plate 40 and of the plate 33 will be determined by the position of the stove in the room which is to be heated and various other considerations, the object being to deflect the products of combustion in the direction which shall be most favorable to the extraction and utilization of the heat units.

The top plate 42 of the smoke-chamber is provided near one end thereof with an opening 4.3 for the upward passage of the products of combustion into a radiating-chamber 44, the side walls of which, 4E5, exteriorly engage a flange 4L6, projecting upwardly from the top plate 42. The top of the radiating-chamber has a smoke-exit 47, surrounded by a pipecollar 4L8f0r connection with a pipe through which the products of combustion may be conveyed to a point of final exit. The radiatingchamber also serves to support an ornamental top e9.

An ornamental ring 50, constituting a footrest, is fitted upon the lire-box section of the stove and is supported upon the upper edge of: the base. The bottomand top plates 24: and 34 of the oven and the top plate 42 of the smoke-chamber are extended beyond the side walls of the stove to intercept upwardly-moving currents of hot air and to deflect the same outwardly into the room or apartment where the stove is located.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of this invention will be readily understood by those skilled in the artto which it appertains.

The construction of the stove is simple and inexpensive. The stove, while primarily a heating-stove, may be satisfactorily used for cooking or baking purposes. The stov-e may be easily maintained in a clean and operative condition, and it will be found economical with regard to the expenditure of fuel. As

previously stated, the stove is also adapted for the consumption with equally satisfactory results of various varieties of fuel.

This improved stove maybe manufactured of cast-iron, sheet metalsuch as heavy Russia v ironor any other suitable material or combination of materials, and itrnay be made very neat and ornamental. As to the shape thereof, it may be of circular cross-section, although a quadrilateral shape having rounded corners will probably be preferred.
